ATTACHM ENT FOR PENS.

SPECIFICATION forming part of Letters Patent N 0. 638,556, datedDecember 5, 1899.

Application filed June 21, 1899. Serial No. 721,351. (No model.)

To all whom it may concern.-

Be it known that I, FRANK WM. CAMERON, a citizen of the United States,residing at Departure Bay, in the Province of British Columbia andDominion of Canada, have invented certain new and useful Improvements inPens 5 and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention has relation to pens.

The object of the invention is to provide a pen which by dipping intothe ink will take and hold sufficient ink to increase its writingcapacity without replenishing, thereby saving much time which is nowlost by frequent dipping cf the pen.

With this object in view the invention consists in certain features ofconstruction and combination of parts, which will be hereinafter fullydescribed and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a penillustrating my 2 5 invention. Fig. 2 is a longitudinal sectional view,and Fig. 3 is a detail perspective view, of the attachment removed fromthe pen.

In the drawings the same reference characters indicate the same parts ofthe invention.

1 denotes the pen, which consists of the stafi, pen-socket, andpen-point, these parts being of any well-known or approved constructionand in themselves forming no part of my invention.

2 denotes the attachment, which consists of a spring-clasp 3 in the formof a longitudinal split cylinder. The forward end of this spring-claspterminates in two parallel nibs 4,

which are curved slightly upward, so as to form an ink-chamber betweenthemselves and the back of the pen-point when the attachment is slippedin place upon the pen. Immediately at the rear of these nibs is formed ashoulder 5, so that when laying the pen down the nibs of the attachmentwill always be supported above the surface of the desk and prevent theink running.

In operation the pen is dipped into the well in the usual manner, and alarge supply of ink will be taken up and retained in the pocket formedby the back of the pen-point and the nibs of the attachment, thusenabling the Writer to write from three to five hundred words withoutagain dipping his pen.

The attachment is of such construction that it may be applied to any ofthe common forms of pens now in use and with but slight changes may beapplied to any form of pen.

It will of course be understood that vari- 0115 changes in the form,proportion, and the minor details of construction may be resorted towithout departing from the principle or sacrificing any of theadvantages of this invention.

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is-

As a new article of manufacture, an attachment for pens consisting of aclasp in the form of a slitted sleeve, and provided at its forward endwith integral parallel nibs. which are curved upward above the plane ofthe sleeve and thence downward to form an arch, the points of the nibsbeing adapted to bear upon the nibs of the pen, said sleeve beingprovided with an integral shoulder pressed upward upon the material andprojecting above the plane of the arched nibs, substantially as and forthe purpose set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

FRANK NM. CAMERON.
